This CL refactor unittests in std140_test.cc, and add exhaustive parameterized unittests in std140_exhaustive_test.cc. In std140_test.cc, only test Std140 transform result for `mat2x2<f32>` for matrix used as array element type and `mat3x2<f32>` otherwise, and keep the source and expected programs as plain WGSL code to ensure the readablity. In std140_exhaustive_test.cc, all matrix shape and different constant index are tested using parameterized WGSL code, at the cost of readablity. This CL prepares for supporting f16 in Std140 transform by allowing testing all shape of f16 matrix as well by simply adding parameters.

Dawn, a WebGPU implementation
Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard.
More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.
Dawn provides several WebGPU building blocks:
- WebGPU C/C++ headers that applications and other building blocks use.
- The
webgpu.hversion that Dawn implements. - A C++ wrapper for the
webgpu.h.
- The
- A "native" implementation of WebGPU using platforms' GPU APIs: D3D12, Metal, Vulkan and OpenGL. See per API support for more details.
- A client-server implementation of WebGPU for applications that are in a sandbox without access to native drivers
- Tint is a compiler for the WebGPU Shader Language (WGSL) that can be used in standalone to convert shaders from and to WGSL.
